Standards Covered
- science.ks3.y1.t3.s6National Curriculum (England) · Science · Year 3 (KS2) · Grade 3explain that some changes result in the formation of new materials, and that this kind of change is not usually reversible, including changes associated with burning and the action of acid on bicarbonate of soda.
- science.ks3.y1.t3.s5National Curriculum (England) · Science · Year 3 (KS2) · Grade 3demonstrate that dissolving, mixing and changes of state are reversible changes
